Motherboard: MSI PC Pro Z370

After just over a year of working fine my motherboard has stopped recognising the CPU (the EZ debug light for CPU stays on and the machine doesn't post). The issue started a week ago however at that point the computer would turn on if switched off at the power supply for a few minutes it would turn on. Now, on the other hand, the machine refuses to turn on at all even after a full power off.

I believe this could be to do with me accidentally shorting out one of the USB ports by screwing around with a disassembled keyboard.

I have tried swapping out the CMOS battery and removing all of the front USB port connections to the motherboard.
 
I highly doubt it. If there was visible signs of which components have failed a professional might be able to fix it but I would expect a new motherboard to be significantly cheaper.

Trouble is this is an educated guess, you will only know if it’s the motherboard by trying a different one.
Fuuuuuuuuuuuuck, Ok, Thanks for the help :)
